PUMP.

SPECIFICATION forming part of Letters Patent No. 393.565, dated Nwember 1888' Application filed October 20, 1887. Serial No.252,892. (Nomodoh) T0 aZZ whom it may concern.-

Be it known that 1, WILLIAM KEAST, of Russell Gulch, in the county of Gilpin and State of Colorado, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved pump specially adapted to raise impure water from mines and other places, and to separate the impurities from the water before the latter reaches the surface.

The invention consists in the construction and arrangement of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my improvement. Fig. 2 is a central sectional elevation of the same, and Fig. 3 is a perspective view of the suction-box with parts broken out to show the arrangement of the suction-valves.

The cylindrical bucket A, of suitable length and diameter, is connected at its upper end by a rod, B,with the pump-operating mechanism, of any approved construction. In the upper end of the bucket A is placed a double flap or butterfly valve, D, and in the bottom of said bucket A is arranged a similar valve, E. The bucket A operates in a barrel, F, provided in its lower part with the tube G, supporting a stufiing box, H, into which fits a gland, Lheld on rods J, extending upward and screwing in flanges of a second stufling-box, K, supported on the first stuffing-box, H, by semicircular brackets N.

In the stufilngbox K is fitted a gland, L, held on said rods J and placed opposite the stuffing-box I. Both stufiingboxes I and K can be adjusted from the outside on the rods J, as the semicircular brackets or supports N permit access to the glands. In the upper stuffing-box, K, is formed on the inside an inclined spiral groove, K, opening at its lower end into a down wardly-extending pipe, K", leading to a suitable receptacle for carrying away the sand discharged by said pipe K. In the upper end of the stuffing box K, above the spiral groove K, is formed an opening, K closed on its outside by a suitable cover, and serving for cleaning the inclined spiral groove K in case it is chokedup with sand or other impurities.

0n the lower end of the tube G of the working-barrel F is secured the suctioubox 1?, divided by a central partition into two compartments, P and P of which the former conneets with the lower end of the bucket A, and the compartment P leads to the suction-pipe P, extending downward in the usual manner. In the compartments P and P are held the valves Q and B, respectively, of which the valve Q is fulcrumed at Q, and is provided on one side with an extension-arm, Q", held above a pivoted arm, S, held in its lowermost position, as shown in Figs. 2 and 3, by a spring,- S, pressing with its free end on the top edge of said pivoted arm S. The free end of the pivoted arm S is connected with a rod, S, extending through the top of the suction-box P 'to the outside, and the outer end of said rod S is connected to one end of a cord or rope, S, which passes upward and over a double pulley, T, and carries at its other downwardlyhanging end a handle, S.

The valve It in the compartment P of the suctionbox P is fulcrumed at R, and is also provided with a sidewiseextending arm, It", held over a pivoted arm, U, on which acts a spring, U, so as to hold said pivoted arm U in its lowermost position, as shown in the drawings. The free end of the pivoted arm U is connected with a rod, U extending upward and through the partition in the suction-box P to the outside. The outer end of the rod U" is connected by one end with a rope or cord, U, extending upward and passing over the double pulley T, and carrying on its other end a handle, U.

The upper end of the stuffing-box Kis connected with the usual tubes, 0, leading to the outside, and in the lower ends of said tubes 0 opens a pipe, V, extending downward and provided with a valve, V, and leading through one side of the suctionbox P into the upper compartment, P, and carrying at its inner end a perforated branch arm,V", which partly encircles the valve Q. so that when the operator opens the valve V the water in the tubes 0 ICO can pass through the pipe V into the perforated branch pipe V and from the latter sprays on the valve Q in its seat, whereby the latter is cleaned of impurities when clogged up.

The operation is as follows: The bucket A. is set in motion in the usual manner by the pump-operating mechanism, whereby the water is drawn through the suctionpipe P and the valves R and Q into the suction-box P, and from the latter through the butterfly-valve E into the hollow bucket A, from which it is discharged at its upper end through the butterfly-valve D into the upper end of the stuflingbox K and the tubes 0. The water discharged from the bucket A into the upper part of the stuffing-box K and the tubes 0 usually carries a large amount of sand and other impurities, which settle into the spiral groove K, and pass down the same, on account of its inclination, into the pipe K'flwhich discharges into a suitable receptacle for removing the sand. The glands L and I of the stuffing-boxes H and K can be easily adjusted from the outside without stopping the operation of the pump, as free access is had to said glands L and I. In case the valves Q and R get clogged up very seriously, the operator pulls on the handle S" or U", whereby the cord S or U is set in motion and pulls on the respective rod 8* or U", so that the pivoted arm S or U is swung upward, thereby lifting the respective valve Q or R as said pivoted arms S and U come in contact with the extensions Q and R of the valves Q and B. At the same time the operator opens the valve V in the pipe V, so that water from thetubes 0 passes down on the top valve, Q, and through its seat, and washes all impurities which clog the valves out of the suction-- box P. The water naturally passes from the first chamber, 1, into thelower compartment, P",when the valve Q is opened, as above stated. As soon as the operator releases his pull on the handles U and S, the spring S or U presses on the pivoted arm U or S, and causes the latter to swing downward into its normal position, so that the valve Q or R closes by its own weight. Thus it will be seen that l am enabled to clean the valves Q and B, when clogged up, without stopping the pump and without removing the suction-box P. It will further be seen that by using two valves in the suction box P, I lessen the possibility of a breakdown.

One ofthe valves, Q or B, may be put .Out of motion by pulling the corresponding rod, S or U", to its uppermost position. The packing in either of the stuffing-boxes H or K can be tightened, in case it gets loosened at any time, without stopping the operation of the pump.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, isr- 1. In a pump, a suction box provided with a valve carrying an extension, in combination with a pivoted arm held below said extension, a spring pressing on said pivoted arm, and means, substantially as described, for raising said pivoted arm, as set forth.

2. In a pump, the combination, with asuctioirbox provided with two compartments and avalve in each of said compartments, of a pipe leading into theupper compartment of said suction-box, said pipe being connected with the pump-tubes and provided with a valve, so as to discharge water into said compartment, substantially as shown and described.

3. In a pump, a suction-box provided with two compartments, a pivoted valve in each of said compartments, and means, substantially as described, for raising either of said valves from the outside, in combination with a tube having a branch pipe at its lower end extending into the upper compartment of the suction-box, a valve formed on said tube, and the tubing of the pump into which leads the upper end of said tube, substantially as shown and described.
